A website dedicated to the poetry of financial disaster~
-## Install
+## Installation
+
+### Install & Setup
First up, `virtualenv`:
pip install -e .
+Now that we've got all the deps, we'll want to create the database.
+
+ >>> from crisishaiku import app, db, User
+ >>> db.create_all()
+
+You'll see it blorp out some SQL. Let's make sure it worked.
+
+ >>> u = User('leigh', 'trouble@crisishaiku.com')
+ >>> db.session.add(u)
+ >>> db.session.commit()
+
+Yet more SQL, and hopefully no error message. Hooray!
+
+Finally, run the server:
+
+ bin/server
+
+And point your browser at http://localhost:5000/ -- you should see the request
+blow by. Hello, world!
+
+Oh, and finally: as a convenience, `bin/server` will attempt to activate the
+virtualenv if one isn't already active (as obviously I find that obnoxious
+and always forget).
